Look at the height of Wilt's jump at 5:18...that is a true 1-step vertical jump, not even going straight up....he cleared at least 36" on this IN-GAME jump. You can tell cuz his head looks at the rim, and look at the air under his feet with respect to the other players on the floor....you can't deny Wilt was an incredible 7-foot athlete beyond his sheer size.
